3(x - y)(x + y)
3x2 -14x -24 can be factored as (3x + 4)(x - 6).
(3x - 8)(8x + 5)
3x^2 + 10x + 8 = (3x + 4)(x + 2)
6xyz(3x + 2y + z)
33(3x - 2y + z)
3x(x - 5)(x + 5)
(x2 + 3x + 5)(x2 - 3x + 4)
(3x^2 - 4y^2)(3x^2 + 4y^2)
That can be factored to (3x - 5)(3x - 5) or (3x - 5)2
(2x - 3)(3x + 2)
(11x - 2)(3x - 5)
3x3 - 3x2 + 2x - 2 = 3x2(x - 1) + 2(x - 1) = (3x2 + 2)(x - 1)
